PATENT OFFICE.

BARTON PICKERING, OF DAYTON, OHIO.

IMPRovED LADDER.

Specification forming part 4of Letters Patent No. 54,767. dated May 15, 1866.

To all whom 'it may concern:

Be itknown that I, BARTON PIGKEEING, of Dayton, in the county of Montgomery, in the State of Ohio, have invented a new and Improved Ladder 5 and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon. 4

The nature of my invention consists in connecting to the upper rounds of the ladder a platform with catches on the under surface to prevent the ladder from spreading, the platform also serving to stay and strengthen the ladder when extended, the ladder being used either as a step or ordinary ladder.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The ligure represents a perspective view of the ladder.

Two ladders,A and B, are constructed in the usual manner, having` rounds ff. These are connected at their upper ends by the bent round f', which round is thus bent so that the platform C, resting on the rounds d and c, will not prevent the two parts of the ladder being brought in a line when extended. The rounds d and e support the platform, and on the under side of which are several catches, which catches pass over the round and prevent the ladder from spreading.

The ends of the part A, projecting to catch on the round e Awhen extended, may be dispensed with, and the platform used alone to hold the ladder when extended.

One end of the platform is irmly attached to the round d by staples or otherwise. Suit able oriices are made in the platform for the feet when the ladder is extended. The platform serves the double purpose of staying the ladder when extended, and forms a convenient platform on which to stand.

What I claim as myinvention, and desire to secure by Letters Patent, is-

The platform O, provided with catches u n, the orifices o, and bent round f', in combination with the ladder A B, having projections on the part A, substantially as described, and for the purpose set forth.

BARTON PIOKERING.
